Your sister

"What's going on in there?" Asks your sister.

Great more fun you think to yourself.

"Go unlock the door and bring her here" you say to your mom.

She goes and opens the door and then brings your sister to the bathroom.

You were about to make your mom close the door but remember your dad is at work.

Now both your mom and sister are in the bathroom and you say to your mom,"Turn on the shower."

You watch her turn on the shower.

"Strip" you say to both your mom and sister.

Your mom strips first. She take off her white top and her pink bra. Her DD tits burst out. She removes her skirt and panties to reveal her shaved pussy.

Then you return your attention to your sister as she removes her black top to reveal her small tits. She removes her leggings and panties for you to see her huge ass burst out.

"Bring a vibrattor and play with yourself while I get mom." You say to your sister.

She exits the bathroom and returns with a vibrator. She spreads her legs out of the bathroom floor and plays with herself.

"Don't cum until I tell you to" you say to her.

"Now you go get all the sex toys you have," you say to your mom.

She exits the bathroom and comes back with a pile of sex toys. You grab the vibrator and make her go into the shower.
